TLV320AIC33IGVX

Codecs Overview

The TLV320AIC33IGVX is a low-power stereo audio CODEC designed for portable audio and telephony applications. It features a stereo audio DAC with a 100-dBA signal-to-noise ratio and a stereo audio ADC with a 92-dBA signal-to-noise ratio. The device supports data resolutions of 16, 20, 24, or 32 bits and sampling rates from 8 kHz to 96 kHz. It includes ten programmable audio input pins and seven audio output drivers, capable of driving 8-ohm speakers at 500 mW per channel. Power supplies include an analog range of 2.7 V to 3.6 V, a digital core range of 1.65 V to 1.95 V, and a digital I/O range of 1.1 V to 3.6 V. The component operates within a temperature range of -40°C to +85°C and is housed in a 5x5 mm 80-ball MicroStar Junior BGA package.

Codecs Feature Summary

• Features automatic gain control (AGC) and programmable microphone bias levels for optimized recording paths.
• Supports flexible clock generation through a highly programmable PLL compatible with various master clock inputs.

Codecs Applications

• Smartphones and PDAs requiring compact audio solutions
• Portable computing devices including laptops and tablets
• Communication equipment such as VoIP phones and modems
• Entertainment devices like MP3 players and handheld gaming consoles

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure package and temperature grade alignment. Confirm that the selected variant matches the required interface protocol and power supply specifications for the target design. Cross-reference the part number with official Texas Instruments documentation to validate availability and compliance status before finalizing procurement plans.

Codecs Selection Notes

Select this component when a single-chip solution for both analog-to-digital and digital-to-analog conversion is required in space-constrained designs. Ensure the system architecture supports the necessary voltage domains for analog, digital core, and I/O supplies. Evaluate the need for integrated headphone and speaker drivers to determine if external amplification can be omitted, thereby reducing bill of materials and board area.
